JOHN PETERS, OF ST. LOUIS, MIS$0URL PROPELLING DEVICE FOR FLYING-MACHINES.

Specification of Letters Patent.

Application filed October 29, 1910.

To all whom it may concern:

Be it known that I, JOHN PETERS, acitizen of the United States, residing at 2653 Ohio avenue, in the city of St. Louis and State of Missouri, have invented a new Propelling Device for a Flying-Machine.

My invention relates to the propelling power of a flying machine and the objects of my device are; first, to raise a flying machine immediately; second, to afford facilities for controlling the direction of the machine; third, to afford facilities for regulating the speed of the machine; fourth, to prevent the machine from capsizing. l attain these results by a mechanism illustrated in the accompanying drawings; in which Figure l is a top view of the propeller with its blades A and B; Fig. 2, a side view of the same propeller. Figs. 3 and 4: and 5 are detailed views of the plates numbers 5 and 6 and 7 These numbers refer to the same parts throughout the several views.

In Fig. 1 number 1 gives a view of the axle which is made of steel tubing. On each end of the axle is fastened a T shaped casting consisting of arms 2 and 3. The arm 3 of the T shaped casting is at a right angle with the axle. Through said T shaped casting passes a continuous propeller arm. This propeller arm, designated in the drawings by number 4, is made of steel tubing, and at an equal distance from the center of the aforesaid propeller arm are sets of ball bearings housed by the above mentioned T shaped casting. These ball bearings allow the propeller arm to move freely. Fastened on the propeller arm are two plates designated in the figures by numbers 5 and 6. These plates 5 and 6 are at right angles to each other and are fastened by a set-screw number 13 on the propeller arm at each end of the T shaped casting. The T shaped casting number 3 rotates with the axle and turns with itself the propeller arm. At each end of the propeller arm is fastened a blade, said blades being designated in the drawings by letters A and B. These blades A and B are offset from the center and are set at right angles to each other, so that when one blade presents its flat side the other will cut the air.

Fig. 2 represents the propeller in motion. The blade B presents its flat side while blade A cuts the air. Numbers 9, 10, and 11 show the support of the propeller arm. Number 7 designates a plate which can be rotated to the extent of 180 degrees by means of the lever number 8. Number 12 is a roller fastened to the plate number 7. The plates 5 and 6 hold the propeller arm in position as they glide along plate number 7.

In Fig. 3 plate number 5 has reached the point where it leaves plate number 7 and plate number 6 has arrived at the point where it will meet the roller number 12, as is shown in Fig. 4. This roller number12 will turn plate number 6 to the extent of 90 degrees and along with itself the propeller arm so that blade B which before stood horizontal will now present its flat side and blade A will stand horizontal. The blades A and B are offset from the center of the propeller arm as is indicated by the drawings. On account of this ofi'- set the blades turn automatically. For as soon as plates 5 or 6 leave plate 7 the blades A or B will turn toward the offset side to the extent of 90 degrees. This automatic turning of the blades operates only when the machine has reached a certain speed; when the machine is started and while running at a very low speed the roller number 12 will turn the blades as the plates 5 and 6 meet the roller alternately.

Fig. 5 shows the check-stop. This checkstop consists of the filing of each end of the T shaped casting where they meet the plates numbers 5 and 6, and of the filing of the plates numbers 5 and 6 where they meet the T shaped casting so that propeller arm can oscillate only to the extent of 90 degrees.

I am aware that prior to my invention boat paddlers With turning blades have plate carrying a roller, said roller adapted been invented; which act on a substantially to contact with the plates on said propeller 10 different system and for a different purpose. arm and thereby to feather said blades.

Therefore: I c airn In a propelling device for air craft, a JOHN PETERS propeller arrn carrying blades, said blades Vitnesses: being ofiset from center, fixed plates car- HENRY J. VVEsTHUEs, ried by said propeller arm, an adjustable SIMON FoRsTER.
